Description

Technical Field

[0001] The utility model relates to the technical field of reaction equipment, and particularly relates to an O-shaped multi-functional tubular reaction device. Background Art

[0002] With the development of economy and society, especially the development of new quality productivity proposed by relevant regulations, continuous and intelligent production has become an inevitability and social consensus. All walks of life have shifted from intermittent production to continuous and intelligent production. Chemical production is increasingly developing towards the characteristics of energy conservation and emission reduction, safety and high efficiency, and multi-function in one machine. The reaction device, as an important link in chemical production, is no exception.

[0003] Generally, a reactor is composed of a single unit, with dispersed reactions, large floor area, and manual intermittent operation. It is difficult to guarantee safety, environmental protection, and production indicators. To meet the requirements of safety, environmental protection, and energy conservation, continuous reaction, safety interlock, centralized absorption of waste gas, and unified control of indicators are implemented. Through intelligent feeding, the accuracy of the feeding ratio is increased, and propeller propulsion is realized. Compared with traditional stirring, the reaction rate is greatly accelerated. However, the heat required for the reaction or the reaction heat generated is completed by a heat exchanger with a large area, which not only ensures the safety of the reaction but also shortens the reaction time. The required indicators are controlled online to achieve production stability.
